Technical Field

[0001] The utility model is applicable to the field of wastewater treatment equipment and provides a wastewater ozone catalytic oxidation device. Background Art

[0002] Ozone catalytic oxidation technology is a highly efficient sewage treatment technology and a hot technology in the sewage treatment field in recent years. The strong oxidizing property of ozone can directly oxidize organic matter in water into carbon dioxide and water, or oxidize and decompose large molecular organic matter into small molecules to make it easier to decompose them into small molecules and make them easier to degrade. In actual operation, sewage treatment is achieved by mixing ozone with sewage and then passing it through a catalyst. However, in actual operation, due to the poor solubility of ozone in water, the water-gas mixing method of simply injecting ozone into sewage through pipes is inefficient, and ozone cannot be fully and evenly mixed in the sewage. Utility Model Content

[0003] To this end, the utility model provides a wastewater ozone catalytic oxidation device. In the sewage ozone mixing device of the device, high-pressure ozone gas is used to drive the pneumatic motor, and the ozone dispersion branch pipe is driven to rotate by the pneumatic motor. At the same time, the air outlet end of the pneumatic motor is arranged on its rotating drive shaft. In this way, while the rotating drive shaft drives the ozone injection pipe to rotate, ozone gas can also be injected into the ozone injection pipe at the same time. In this way, the ozone dispersion branch pipe can simultaneously have the two functions of injecting ozone and stirring to accelerate ozone fusion.

[0007] The tank body support is arranged below the reaction tank body and is fixedly connected to the reaction tank body.

[0008] Furthermore, the ozone injection pipe is rotatably arranged in the mixing chamber, and an injection pipe driving device is fixedly connected to the outer side wall of the mixing chamber. The injection pipe driving device is drivingly connected to the ozone injection pipe and is used to drive the ozone injection pipe to rotate.

[0009] Furthermore, the injection pipe driving device is a pneumatic motor, which includes an air inlet port, an air outlet port and a rotating drive shaft. The rotating drive shaft is fixedly connected to the ozone injection pipe, the air outlet port is arranged on the rotating drive shaft and is connected to the inside of the ozone injection pipe, and the air inlet port is used to connect to the ozone supply pipe.

[0010] Furthermore, the sewage inlet pipe includes a sewage diffusion coil, which is arranged at the lower part of the mixing bin and has a spiral structure, and a plurality of sewage injection nozzles are arranged on the sewage diffusion coil.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the scheme of the utility model, a mixed gas containing a certain proportion of ozone is pressurized and then connected to an air motor as a power source of the air motor, thereby driving the ozone injection pipe and the ozone dispersion branch pipe to rotate to achieve a stirring function, and the ozone mixed gas is directly discharged from the air outlet port of the air motor into the ozone injection pipe, and finally sprayed from the ozone gas injection port of the ozone dispersion branch pipe into the mixing chamber to mix with the sewage to be purified. This direct drive mode of ozone gas ensures that the mixing and stirring of ozone gas and sewage is achieved without the need for power supply, thereby improving the ozone mixing efficiency and reducing the risk of leakage caused by practical electricity.

[0017] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

In this embodiment, the injection pipe driving device 22 is a pneumatic motor, and the pneumatic motor is a prior art. Generally, the pneumatic motor includes an air inlet port, an air outlet port and a rotating drive shaft. By connecting the pressurized gas from the air inlet port, the pressurized gas drives the rotating drive shaft to operate through the mechanical driving structure in the pneumatic motor, and finally is discharged from the outlet port. In this embodiment, the rotating drive shaft is fixedly connected to the ozone injection pipe 23 and is connected to the ozone injection pipe 23. The ozone injection pipe 23 is internally connected, and the air inlet port is used to connect the ozone supply pipe, and the air outlet port is arranged on the rotating drive shaft, so that the pressurized gas will enter the ozone injection pipe 23 after being discharged from the air outlet port. In this embodiment, a high-pressure ozone mixed gas mixed with a certain proportion of ozone is directly used as the power source of the pneumatic motor, and it can also be directly sprayed into the sewage through the ozone gas injection port to mix with the sewage. In this way, the ozone dispersion branch pipe 24 can also simultaneously complete the two functions of injecting ozone gas and stirring and mixing sewage and ozone gas, which greatly improves the mixing efficiency of ozone in sewage. The injection of sewage depends on the sewage inlet pipe 26, one end of the sewage inlet pipe 26 is arranged outside the mixing bin 21, and the sewage inlet pipe 26 includes a sewage diffusion coil, which is arranged at the lower position in the mixing bin 21. At the same time, the sewage diffusion coil structure is spiral, and a plurality of sewage injection nozzles are arranged on the sewage diffusion coil. The sewage to be treated is evenly injected into the mixing bin 21 through the sewage injection nozzle.

[0019] This implementation works as follows:

[0020] The sewage to be purified is connected through one end of the sewage inlet pipe 26, and is evenly injected into the mixing chamber 21 through the sewage injection nozzle of the sewage diffusion coil. At the same time, the pressurized ozone mixed gas is connected through the air inlet port of the pneumatic motor. Under the action of the high-pressure ozone mixed gas, the rotating drive shaft of the pneumatic motor begins to rotate, and the rotating drive shaft begins to drive the ozone dispersion branch pipe 24 to rotate and stir in the mixing chamber 21. At the same time, the high-pressure ozone mixed gas enters the ozone injection pipe 23 from the air outlet port of the pneumatic motor, and is finally sprayed from the ozone gas injection port of the ozone dispersion branch pipe 24 into the mixing chamber 21 to mix with the sewage to be purified. The sewage and the water-gas mixture of ozone mixed in the mixing chamber 21 are finally sprayed upward from the mixed water-gas nozzle 25 at the upper end of the mixing chamber 21 into the reaction tank body 1 as the liquid level in the mixing chamber 21 increases. At the same time, the catalyst required for the reaction is added into the tank body from the catalyst addition port 11 of the reaction tank body 1. The sewage to be purified undergoes a catalytic oxidation reaction in the reaction tank body 1, and finally the sewage is purified.
